Engineered Earth Armoring System

The most advanced and resilient

technology for preventing severe

erosion and stabilizing surficial

slopes is PROPEX® Armormax®

PROPEX Armormax is composed of

High Performance Turf Reinforcement

Mat (HPTRM) and Engineered Earth

Anchors that work together to lock soil

in place and protect against hydraulic

stresses.

High Performance Turf Reinforcement Mat

Solmax’s HPTRM technology features patented

ultraviolent stabilization and high tensile strength to

provide up to 75 years of slope protection and erosion

mitigation, even in environments with direct exposure

to sunlight. Additionally, the HPTRM is designed to

accelerate vegetative growth, exhibit high resiliency,

and feature strength and elongation properties to

limit stretching in saturated conditions.

Engineering Earth Anchors

Corrosion resistant Engineered Earth AnchorsTM (EEA)

secure the HPTRM to the ground. EEAs are designed

to provide resistance to shear and lateral forces, and

embed beyond the predicted plane of failure. The

PROPEX Armormax system uses either a B1, B2, or B3

anchor depending on the application and environment.

Tested. Proven. Trusted.

The U.S. Army Corp of Engineers (USACE)

commissioned Colorado State University to test

erosion resiliency of HPTRMs for 500-year hurricane

overtopping conditions. Testing showed that Armormax

provided increased levee resilience and reduced the

risk of breaching caused by overtopping. The USACE

has now installed more than 1 million square yards of

PROPEX Armormax on coastal and river levees.

Design and Performance

• Provides permanent erosion protection for

up to 75 years

• Withstands extreme hydraulic stresses
• Provides temporary shoring and stabilization

for constructed slopes

• Resistant to non-hydraulic stresses from debris

and mowing and maintenance equipment

• Resistant to fire using non-halogen fire

retardant technology

• Highly UV stabilized for applications with little

or no vegetation

• Outlasts other slope reinforcement methods

yielding significant cost savings

• Ease of installation reduces time and labor costs
• Lightweight and easily transported into areas

with access challenges

• Reduces the amount of space needed for a

right-of-way

Environmental

• Recognized by the EPA as Best Management

Practice (BMP) for improving water quality

• Verified carbon footprint is up to 30 times smaller

than traditional hard armor

• Recognized by FEMA as a nature-based solution
• Filters sediment and pollutants to improve

water quality

• Encourages infiltration of water back into

the ground water table

• Proven to reduce erosion and reinforce

vegetation for low-impact, sustainable design

• Yields a vegetated solution that is more

aesthetically pleasing than traditional hard

armoring solutions

• Maintains cooler water temperature than

traditional hard armoring, which is healthier

for aquatic habitats

• Arid and semi-arid environments

where vegetation densities of

<30% are anticipated

• Earthen Dams and Spillways
• Roadway Embankments
• Canals/Stream Banks
• Steepened Slopes
• Channels
• Levees
• Areas prone to wild fires
• Defensible spaces
